Thermal Paste: Critical for Cool Operation
Reliable heat transfer is vital in electronics - from laptops and desktop PCs to embedded projects and sensor nodes. Thermal paste (also called thermal grease or thermal compound) fills tiny gaps between components and heat sinks, ensuring efficient cooling. Whether you're building a PC, repairing an amplifier, or assembling a custom sensor, the right paste improves performance and device longevity.

- Pick up at Communica's branches or choose reliable courier delivery anywhere in South Africa.
- Brands suited for PC, embedded, and industrial electronics - from leading global names to value options.
- Get VAT invoices automatically for student, business, or institutional procurement.
Types of Thermal Paste Stocked at Communica
| Type | Key Features | Suitable For | Popular Brands |
|---|---|---|---|
| Silicone-based | Good thermal conductivity, non-electrically conductive, affordable | General electronics, beginner PC builds | Cooler Master, AG Termal, Honywell |
| Ceramic/Metal Oxide | Improved conductivity, thick, easy to spread | Laptops, microcontrollers, industrial | Halnziye, Dow Corning |
| Silver-based | Premium performance, highest thermal conductivity | High-power CPUs, overclocked builds, power modules | Arctic Silver, Halnziye |
Local insight: Silicone-based and ceramic compounds are most widely stocked at South African distributors for general use, while premium silver-based options are available for enthusiasts and pro repairers. Always check compatibility with your component surface (particularly for laptop and SMD work) and confirm availability for urgent orders.
How Much Thermal Paste Do You Need?
Most syringes and tubes range from 1g to 30g. For a single CPU application, 1-2g is more than sufficient. Larger projects or repeated maintenance on lab test gear - such as voltage regulators, MOSFETs, or amplifier ICs - may require 5-10g. Always apply a thin, even layer to avoid spillage or electrical shorts.

What to Look for When Ordering Online
- Thermal Conductivity (W/mK): Higher numbers (typically 2-8+ W/mK) mean better performance for demanding builds.
- Viscosity: Thicker pastes are less messy but may be harder to spread on small chips (check datasheets for specs).
- Electrical Conductivity: Most pastes are non-conductive, but always confirm type before using near fine SMD/PCB traces.
- Operating Temperature Range: Key for industrial or outdoor projects in South Africa - standard silicone grades operate from -50 degreesC to 200 degreesC.
- Brand provenance: Prefer reputable names or familiar datasheets, especially when heat dissipation is critical.
Typical Applications & Tips
| Application | Recommended Paste | Example |
|---|---|---|
| PC & Gaming CPU | Silver or ceramic paste, 2-8 W/mK | Intel/AMD with active air or liquid cooler |
| GPU or Laptop Repair | Medium-high conductivity, non-conductive types | Replace dried compound under heatsinks |
| Embedded/Industrial | Silicone-based, for TO220, TO3, or similar | Power supplies, regulators, amplifiers |
South African scenario: Extended summer heat can push local labs and PCs near their thermal limits. When ordering online, choose quick collection or rapid courier delivery to keep your repairs and builds on schedule.
Order Process and Local Fulfilment
Ordering from Communica is straightforward: add the required paste to your cart, check live stock availability, and select collection or courier dispatch options. For institutions or companies, account quotations and VAT invoicing are supported. Stock is held in Samrand, with branch pickup also available in Cape Town and Pretoria CBD. For urgent needs, confirm branch stock before heading out or use the online enquiry for bulk requests.
Troubleshooting & Best Practices
- Remove old or dried paste thoroughly with isopropyl alcohol for best thermal transfer.
- Only a thin, even film is necessary; excessive paste may insulate instead of cool.
- If your system's temperatures remain high after applying new compound, double-check heatsink contact and application area.
